The writings of Apostles and Evangelists, the Discourses of our Divine Lord Himself, abound in short formulae; and the intervening matter on such occasions is constantly an integral sentence, which occasionally may be discovered from its context without evident injury to the general meaning of the place.

On the other hand, many modern scientists accept the basic tenet that knowledge of the natural world is to be expressed in mathematical formulae, which is rightly regarded as a central Pythagorean thesis, since it was first rigorously formulated by the Pythagoreans Philolaus

And in general it follows, if man and such things are substance, that none of the elements in their formulae is the substance of anything, nor does it exist apart from the species or in anything else; I mean, for instance, that no ‘animal’ exists apart from the particular kinds of animal, nor does any other of the elements present in formulae exist apart.

If I follow the usual ethnic / religious / cultural portmanteau formulae all I can come up with is "A Bit Middle Class West Country-Surreian-Londoner", viz a mash-up of my grandparents 'birthplaces and backgrounds.

I am most grateful to Prof.O. Strunk for having drawn attention to the passages [some of the "formulae" of Byzantine Chant] in his article on "The Notation of the Chartres Fragment" to which frequent reference will be made in these pages.
